Abstract

In a conventional vertical axis wind turbine, in order to carry the generated current away from the coils, it is necessary for the shaft to be hollow so that suitable wiring can pass through the shaft. However, the shaft carries the weight of the generator and must withstand in-service loads. As a result, such shafts are conventionally constructed from relatively high strength steel so as to give them the necessary strength and rigidity. A vertical axis wind turbine apparatus is disclosed. The wind turbine has: a blade portion 6; a generator 8 comprising a stator 12 having a plurality of coils 20 and a rotor 10 having a plurality of magnets 22, the rotor 10 being connected to the blade portion 6 such that rotation of the blade portion 6 and rotor 10 generates a current within the coils 20; a stator 12 comprising a shaft 114, the shaft 114 having a first terminal portion 34 and a second terminal portion 36 separated from one another by an insulator 38, the first and second terminal portions 34, 36 being electrically connected to the coils 20; wherein the shaft 114 is received by openings 40’, 40’’ provided in first and second conductive rails 4b’, 4b’’ so as to support the generator 8 and blade portion 6 and such that the first and second terminal portions 34, 36 are electrically coupled to the first and second conductive rails 4b’, 4b’’ respectively to carry the current from the coils 20. The first and second rails 4b’, 4b’’ are thus able to carry the current generated in the generator 8 to which the shaft 114 is connected.
